WOBURN, Mass. — A lawyer for an Irish nanny charged with murder in the death of a 1-year-old girl argued Friday that medical reports indicating that the child suffered bone fractures when she was not in the nanny's care should result in her being released on bail while awaiting trial.

But a prosecutor said the older injuries don't affect the prosecution's allegation that Rehma Sabir suffered severe head injuries during a time when the nanny, Aisling Brady McCarthy, was watching her.
